Reaction Conditions

Reaction Steps

18.0 g (0.13 mol) of potassium carbonate, 121.8 g (3.80 mol) of methanol and 60.0 g (2.00 mol) of paraformaldehyde are initially charged and cooled to −5° C. At this temperature, within 30 min, 262.6 g (2.00 mol) of ethyltrimethylsilanylmethylamine are metered in. The biphasic reaction mixture is stirred at −5° C. for a further 1 h and then warmed to room temperature within 20 min. Within 1 min, 382 g of pentane are metered in. The biphasic reaction mixture is separated and the upper, organic phase is dried azeotropically for 2 h. The organic phase is concentrated and then fractionally distilled. Yield 228.5 g (71%) of a colorless liquid.
